“…In fact, M. spicata has different chemical compositions throughout the world (6-15). According to Karousou et al (1998), M. spicata EO of Greece was characterized by the predominance of Z-piperitone (44.95%), whereas menthone and pulegone were detected at low percentages (0.29 and 0.03%, respectively). These authors reported the presence of menthol with a percentage of 6.49% and also of neomenthol, methyl acetate and limonene at lower rates.…”

In the present investigation, essential oil (EO) and methanolic extract of Tunisian Mentha spicata leaves were tested for their chemical composition and biological activities. Results showed that EO was characterized by the predominance of oxygenated monoterpenes (92.18%), followed by monoterpene hydrocarbons and sesquiterpenes whose respective amounts were 2.74 and 3.1% of the whole EO. The main volatile compound of M. spicata EO was L‐menthone, accounting for 32.74% of the total volatiles, followed by pulegone (26.67%). The phenolic composition of methanolic extracts was determined by reversed‐phase high‐performance liquid chromatography. The major flavonoid component was apigenin with a mean concentration of 38.4 mg/100 g dry weight. M. spicata leave extract tested for their antioxidant and antibacterial activities showed a significant antiradical and superoxide anion scavenging capacity in addition to the great potential for antimicrobial activities against the bacteria tested. PRACTICAL APPLICATIONS Spearmint (Mentha spicata L.) is an aromatic plant belonging to the Lamiaceae family. M. spicata L. is commercially cultivated in many regions of the world. Spearmint oil has economical importance and is used in perfumery, confectionary and pharmaceutical preparations. Tunisia is blessed with a rich source of aromatic plants, many of which have not been previously investigated for their chemical constituents and biological potentials. Among these plants, we can mention M. spicata L. (Lamiaceae), which is largely distributed from the humid to the upper arid regions. This work was carried out as a first step for a chemical and biological activity of Tunisian M. spicata through phenolic and essential oil composition. A further isolation and purification of M. spicata phenolics and volatiles will be associated with an application in food industry as antioxidants, additives for food preservation and for enhancing their nutritional value and organoleptic quality. Furthermore, a pharmacological study could be established through in vivo assays in order to discover new anticarcenogenic, anti‐inflammatory, antimutagenic and other activities of M. spicata. Such results could be used in pharmaceutical formulations, leading to new human drugs from this medicinal plant.

“…This suggests that pot-grown E. citriodora plants respond similarly to diverse types of stress. It is quite puzzling that leaf essential oil concentrations were fairly similar for all growing conditions, especially in light of studies conducted on other plants, suggesting that reduction of solar radiation when plants were shaded significantly reduced essential oil accumulation 30,31 , and that intense solar radiation led to high accumulation of secondary metabolites, including essential oils 24,25,[31][32][33][34][35][36] . The production of secondary metabolites was suggested as part of the plant defense mechanism against radiation, a mechanism that shifts carbon partitioning from vegetative growth to production of secondary metabolites 25 .…”

The influence of light conditions on plant growth and essential oil production of the novel herb Eucalyptus citriodora (Lemon-Scented Gum) was investigated. Pot-grown plants were grown either directly exposed to sunlight or 'shaded' with the least exposure to sunlight (75 % shade) or with intermediate exposure to sunlight (50 % shade). Shaded plants were generally taller, had thicker stems and wider canopies, grew more branches, produced larger leaves, produced more essential oils per plant, produced similar concentrations of the major essential oil components (citronellal, β-citronellol and trans-caryophyllene) in the leaves and produced record high concentrations of (±)-p-menthane-3,8-diol, a component having superior insect repellent properties, than the ones grown under full sun. Plants grown under '50% shade' were likely to be the most productive of leaves and essential oils, either for personal use in tea infusions or for production of leaf-essential oils, potentially having improved capacity for insect repellency.

“…Ioannidis et al (2002), on the other hand, found positive effect of UV-B on total volatile production in sweet basil without any difference in the qualitative or the quantitative composition of essential oils. Karousou et al (1998) studied the chemotype of M. spicata and found that one of them caused a 50% increase in essential oil after UV-B radiation. In the present investigation also the yield of essential oil increased significantly after sUV-B treatment (Fig.…”

Field grown plants of holy basil (Ocimum sanctum L.) were treated with biologically effective supplemental ultraviolet-B (sUV-B) radiation (ambient ?1.8 kJ m -2 day -1 ) to evaluate its effect on specialized oil glands and quantity and quality of the essential oil. The total yield of essential oil increased significantly by 42.0% after sUV-B treatment. Gas chromatography-mass spectrometry analysis showed that most important flavor compounds b-caryophyllene, germacrene-D, ethyl linoleolate, b-elemene and camphenol increased significantly after sUV-B treatment. Moreover, the level of main compound eugenol was not affected significantly. Scanning electron microscopy analysis showed turgidity of oil glands after sUV-B exposure and it was well correlated with the higher yield of essential oil. The result is of specific interest because if other parameters remain constant, sUV-B may affect the production of the essential oil in Ocimum sanctum L.
